What does a normal ECG with normal variations mean?

What does a normal ECG with normal variations mean?

Normal: I think you are referring to the general appearance of the ECG complexes along with timed intervals of conduction. This tells us something about the morphology of the heart (ie is it enlarged or is it damaged), as well as the electrical conduction properties ( which might hint at the risks for arrhythmia). These intervals all have a normal range and variability within that range is normal. ...Read more

What are normal variations in fasting blood sugar? My normal is around 85, recent test showed 98. 30yo m

What are normal variations in fasting blood sugar? My normal is around 85, recent test showed 98. 30yo m

See answer: Fluctuations in blood sugar are quite normal and the rule rather than the exception. Blood sugar values will vary depending on the nutritional content of your diet, the amount of time that has elapsed since your last meal, your level of exercise and activity as well as being potentially influenced by medications and illness and other intangible factors. Your fluctuations are well within normal. ...Read more

Breathing rates: at rest i take about 7 breaths a min, my partner breathes about 24 times a min, normal variation?

Breathing rates: at rest i take about 7 breaths a min, my partner breathes about 24 times a min, normal variation?

Probably....: In order to really compare, you would need to compare minute ventilation. Minute ventilation is defined as the number of breaths you take in a minute multiplied by the volume (size) of the breaths taken. So, you may be taking deeper breaths at a lower rate while your partner may be taking more shallow breaths at a higher rate but your minute ventilation may be identical. ...Read more

No symptoms feel well but why my wbc went from 6.2 and 2 years later low normal at 4.3 .Is this considered normal variation.

No symptoms feel well but why my wbc went from 6.2 and 2 years later low normal at 4.3 .Is this considered normal variation.

Could be: All laboratory results need to be interpreted in the clinical context and the doctor who ordered the tests is usually in the best position to do that. Talk to the doctor who ordered the tests. Having said that, the change in WBC per se is not a cause for concern.
Wish you good health! - Have a diet rich in fresh vegetables, fruits, whole grains, milk and milk products, nuts, beans, legumes, lentils and small amounts of lean meats. Avoid saturated fats. Drink enough water daily, so that your urine is mostly colorless. Exercise at least 150 minutes/week and increase the intensity of exercise gradually. Do not use tobacco, alcohol, weed or street drugs in any form.
Practice safe sex, if you have sex. ...Read more

At a 5w2d scan post ivf, the sac measured 8.5mm, which is almost 4 days behind according to my ob. Is this within normal variation for ivf?

Could be: Gestational sac measurement is pretty inexact for dating, crown-rump length is highly reliable - i can't say whether you're okay ro not, but i'd not jump to any negative or positive conclusions until a 6 week scan, things should be clear then. Best wishes. ...Read more

If hCG levels have a very wide normal variation, than how is it that doctors determine that a level of 634 is typical 2-3 weeks after conception?

If hCG levels have a very wide normal variation, than how is it that doctors determine that a level of 634 is typical 2-3 weeks after conception?

Normal distribution : That value falls within the range (even though it is wide) for that estimated gestational age range. It's similar to saying that a typical birthweight for a full-term newborn is 7lbs, even though we know that the normal full-term birth weights may range from ~5-11 pounds. "normal" or "typical" in the medical sense usially includes ~80-90% of the population. ...Read more

That's fine: They fluctuate wildly even from day to day, with the minor stresses and perhaps microbial exposures of everyday life. Ignore the percentages entirely; the totals are both fine. Keep in mind that they're your friends. ...Read more

Is it normal variation for diastolic blood pressure to elevate by 20-35 depending on posture/exertion/stress, even if temporarily as high as 95+?

Is it normal variation for diastolic blood pressure to elevate by 20-35 depending on posture/exertion/stress, even if temporarily as high as 95+?

The norm: The normal blood pressure response to exercise/stress etc. is for the systolic blood pressure to rise reasonably, but the diastolic pressure normally will decrease widening the pulse pressure. If your diastolic pressure is elevating up to 95 during physical activity, you may have hypertension. You need a treadmill test. ...Read more

Four month old daughter with urate crystals in diaper multiple times. Blood work and urinalysis normal. Something serious or normal variation?

Four month old daughter with urate crystals in diaper multiple times.  Blood work and urinalysis normal.  Something serious or normal variation?

VERY NORMAL!: We se uric acid crystals from the day kids are born. This is normal in infant urine and absolutely no reason to be concerned. In peds we call this "brick dust" in the diapers, but often it's just a pink hue to the urine, depending on what brand of diapers and how absorbent they are. No need to worry. ...Read more

Started Prozac (fluoxetine) 2 months ago. Weight up about 2 lbs with no lifestyle change. Heart, kidney, liver ok. Is this probably Prozac (fluoxetine)? Or normal variation?

Started Prozac (fluoxetine) 2 months ago. Weight up about 2 lbs with no lifestyle change. Heart, kidney, liver ok. Is this probably Prozac (fluoxetine)? Or normal variation?

Not necessarily: When people are depressed they frequently have poor appetite and lose weight. So it stands to reason when their treatment ( in this case the effect of Prozac (fluoxetine) ) begins to work they may regain their appetite and start to gain weight. There are other potential reasons for gaining weight so this should be a topic of discussion with your doctor. ...Read more

How can you detect mood disorders as opposed to normal mood variations ?

How can you detect mood disorders as opposed to normal mood variations ?

Length of time also: Normal mood variations usually don't last as long as a mood disorder, & aren't as intense. For depression, the symptoms have to be present for at least 2 weeks. Also, normal mood variations don't include the changes in sleep, appetite, and energy that depression has. There is also usually something that can improve a "mood variation, " but full depression doesn't respond to such things. ...Read more

Maybe: Orthostatic hypotension is diagnosed in this way, but you need to measure lying, sitting and standing. And you want to wait 3 minutes between positional changes to measure. If you quickly measured, then this may just be normal physiological response to standing. Symptoms of hypotension are dizziness, weakness, blurry vision, sweating. If these are present, try adding extra salt and see doc. ...Read more

What is the normal range of variation for TSH between blood tests taken throughout the year for a person not on any meds?

What is the normal range of variation for TSH between blood tests taken throughout the year for a person not on any meds?

<10%: Tsh is secreted by the pituitary gland as a stimulator of thyroid hormone production. Depending on your thyroid gland function, the TSH value will be reciprocally elevated or decreased. It is a servo mechanism: TSH does down when T4 or T3 (liothyronine) is up. It is a constant fine tuning. But, in general, it does not alter more than 10% during a year. ...Read more

HR rises & falls twice (Up, down, up, down) during each set of inspiration & expiration. Shown in ANS tests. Variation of normal Sinus Arrhythmia? or?

Sinus arrhythmia: Sinus arrhythmia only reflects an exaggeration of a normal behavior. Everyone's HR tends to vary slightly with the normal changes in pressure in the chest with breathing. Your HR should increase with inspiration and decrease with expiration. If this variation is quite obvious, then we call it a "sinus arrhythmia," but it's not generally clinically significant. ...Read more

I am 38 years old. Pregnant 11,6 weeks. The NT shows a variation from 2.6 to 3.0mm. And also a ducto venosos A negative. Is that a normal range for NT?

Genetic screening: It appears that you are undergoing genetic screening. Typically the Nuchal fold is combined with blood testing to help determine the risk of genetic abnormalities. The impedance level through the ductus venosus is sometimes added as a screening tool. Schedule a follow up with your doctor to go over all of your results and so that your risk can be calculated ...Read more

Lab variation issue - If I have normal lipase values at one lab, but elevated values at a different lab, how do I know which lab is "correct"?

Any symptoms?: Why were the tests done? Do you have any symptoms? Both results may be correct as different methods of testing can provide different results. What is the amylase? If the pancreatitis is you concern, a normal amylase would rule that out. For good health - Have a diet rich in fresh vegetables, fruits, whole grains, milk and milk products, nuts, beans, legumes, lentils and small amounts of lean meats. Avoid saturated fats. Drink enough water daily, so that your urine is mostly colorless. Exercise at least 150 minutes/week and increase the intensity of exercise gradually.

Im courious what heart rate variation in percentage could be considered as normal during a 4 minutes measurement at rest?

Depends: It does depend a bit on age, but in general there is data that suggest at rest there is less than a 10 beat per min variation at rest, which approximates out to around 12%. Again this varies on age, medications being taken and underlying disease that one might be afflicted with. Hope this helps. ...Read more
